Polar sea ice size of India vanishes in record heat Antarctica the sleeping elephant beginning to stir? Sea ice extent in Arctic and Antarctic reached record lows in November. Both the Arctic and Antarctic experienced record lows in sea ice extent in November, with scientists astonished to see Arctic ice actually retreating at a time when the region enters the cold darkness of winter.

Sea ice extent in Arctic and Antarctic reached record lows in November

Warm temperatures and winds drove record declines in sea ice at both polar regions in November compared to the 38-year satellite record of ice extent for the month. Arctic sea ice extent averaged 9.08m sq km (3.51m sq miles) for November, which is 1.95m sq km (or 753,000 sq miles) below the long-term average from 1981 to 2010 for the month. Scientists at the National Snow and Ice Data Center (NSIDC) said that Arctic sea ice extent dipped for a short time in mid-November, an “almost unprecedented” event. Sea ice shrank by around 50,000 sq km (19,300 sq miles) in this period, mainly in the Barents Sea.

This decline, which also occurred to a smaller degree in November 2013, removed an area of ice larger than Denmark from the Arctic at a time when sea ice is usually growing. The Great Thaw: mapping Arctic sea ice thickness. As Geographical takes a look at the geopolitical state of the Arctic, Benjamin Hennig maps current ice thickness at the top of the world.

Unveiling his most aggressive plan yet to combat climate change, President Obama on Monday referenced recent dramatic changes that National Geographic made to its atlas because of melting sea ice.

Yes, Mr. President, We Remade Our Atlas to Reflect Shrinking Ice

"Shrinking ice caps forced National Geographic to make the biggest change in its atlas since the Soviet Union broke apart," Obama said during a speech at the White House. (Watch a video of his speech.) He's right. The shrinking of the Arctic ice sheet in the 10th edition of the National Geographic Atlas of the World is one of the most striking changes in the publication's history. After the publication of the atlas in September 2014, the ice has melted even further, notes National Geographic Geographer Juan José Valdés. "The end of Arctic summer is still several weeks away, and it's still too early to say if another record will be broken. As the ocean heats up due to global warming, Arctic sea ice has been locked in a downward spiral. Publication schedules have an impact as well.

Two Maps Show Greenland’s Sudden Melt Season Onset

Red indicates losses. Credit: Polar Portal It appears that Greenland’s melt season is making up for lost time. After a cool spring kept Greenland’s massive ice sheet mostly solid, a (comparatively) warm late June and early July have turned half the ice sheet’s surface into liquid, well outside the range of normal for this time of year. Right Relevance. In April of this year, two Dutch polar explorers, Marc Cornelissen and Philip de Roo, set off from Resolute Bay in the Canadian Arctic.

They were headed for Bathurst Island, a journey of 400km that was due to take around a month. This was part of the Last Ice Survey expedition to gather data about snow and ice thickness for York University, Ontario. They would walk and ski across a region known as the Last Ice Area, where summer sea ice is expected to be most resilient to climate change. A few days into their trip, when they were still in Resolute Bay preparing for the hard month ahead, Philip found Marc’s sled from a previous unsuccessful expedition being used by a local hunter.

In one of the many short voice recordings which they uploaded each day during their journey, Marc talks about what a special feeling it is to be back in the region and how pleased he is to be there with his trusted expedition partner Philip. I first met Marc and Philip in 2005. Businessinsider. Poles of Inaccessibility - the Remotest Places on Earth. Antarctica is the most remote continent, and due to its harsh climate and lack of any roads or trails, its POI may be considered as the most prominent of all POIs.

The location of the POI of Antarctica is 54.9681° E and 83.6978° S, while the distance from this spot to the seashore is 1183.421 km. Arctic Coastal Communities.

Antarctica is in trouble. Its frozen edges, or ice shelves, are disappearing into the ocean faster than we thought. Some have thinned by up to 18 per cent in the past two decades, and the process is accelerating. The most rapidly melting ones are likely to be gone within 100 years. Antarctica may have just set its highest temperature on record. Antarctica, Earth's coldest, most barren continent, may have just set a remarkably unusual weather record. An Argentinian research station on the rapidly warming Antarctic Peninsula recorded a high temperature of 63.5 degrees Fahrenheit (17.5 degrees Celsius) on March 24, according to reports from Weather Underground.

If this is investigated and verified by the World Meteorological Organization (WMO), it could become the highest temperature on record for the entire continent of Antarctica. The warmth at the Esperanza research station came one day after a nearly identical high temperature was logged at another Argentinean base, known as Base Marambio, also located along the Antarctic Peninsula.
